To all whom it'mo'ny concern.' Be it known that We, lnwlnn L. Downs, yofNon? lllrighton, .Benner county, `Pennsylrenie, end donn t?. linnn, ot'llittsbnrg, sNorth Side, Allegheny county, Pennsylre nie, both citizensol the United States, here invented e certain new end. useful DrainConnection, of which the following is especi'm iicetion. Our inventionrelates to drain connections for sinks, tubs, basins end the like.

- Throughout this speciiieetiontor the seke lolf brevity We will.describe the invention es nsed in connection with s sink, lont it is tobe lili understood thet the invention .is applicable equally Well totnbs or any other tublike vessels.

@or invention is designed' to he nsedprincipelly in connection withliiglfrgrnde sinks 2@ or'tubs, the inner snrleces oi which ere coV- eredwith vitreous enamel. Hoeness of the clinrecter of' the dreinconnections which have heretofore been used on enameled, sinks,v it-hssbeen considered necessary to 25 provide e. recess in the sink bottomsurrounding the 'drain opening. lt is exceedingly diioult to properlyenamel motel surfaces having abrupt ongles such es ere ionnd in sinksprovided with such n recess. In epplying the drain connection to sinkshei/ing suoli e recess, the .enamel adjacent to the opening isfrequently crooked or crazed for reasons understood by those skilled. inthis srt. Uur invention voids these dissdvon tages by providing enlenameled sink with e straight Welled drain o ening, the upper Iedge ofwhich immediate y joins the nornnil inner bottom surface ol the sink.'lhc seid sink surface rosy loe mede entirely free from 40 shnrp singlesor abrupt changes in diriwetion.-

The parte of the drain connection which :tre

originally seperate from the sink are ed: ited to the style of the sinkbottom and dlrziin o eninggdescribed and the connection is furtllierconstructed and arranged so that the entirev fluid contents oi' the sinkvmoy be dis charged through the drain opening, there being .no recess ortrop formed within the sink by any port of the appliance which reteinsmy portion of the fluid.

@ne of the objects provided tor by the invention is to provide Ineens inthis kind of e drain connection by whiehthe Weste Weiter tney bestrained and .et the seine time sub stsntislly every drop of the fluidtney pese ont through the drain opening.v l 6e -The use ci our inventionavoids eny tendency to chip orcraze the enamel surrounding the drainopening end et the sinne time the eppeernnce of such portions of theconnecn tion es may be seen frorn Within the sink is 6e very 'ornamentalsindv attractive.

.ln the accompanying drawing we show en exerniililying structure.embodying the involition, het it is to be understood that the inventionis capable of embodiment in dit w ferent forms.

Fig. l is-e top View of the stre-incr by itself.

Reference cherecter 1 designates s. sink or 80 the like, 2 the customary'approximately leyel end horizontal inner bottom surfoce thereof, end 3,the drain opening, usually eironlin', having n. perfectly straightcylindrical VWell passing through the bottoni of the sink. B5

The drain opening is generally surrounded et the outside oi the 'sinkbottom with e cir--` cular boss l to increase the thicknessnnd strength.of the sink bottom et this ,"oint. Sinks-or tn'bs of the class4Withwhich t viis in- 90 vention is generally employed nre nsuellycovered on their inner surfece with 'vitreous enamel but the inventionis also s. plieeble to vessels-Which are not so eneme ed and for thisreason end for the sake of cleerness it is not attempted to show theenamel in the drawing. lt is to be noted es )ecielly the!) the innerbottom sui-hice of t e sink preserves its normel contour directly to the-drein opening end hes no abrupt changes of direction or recesses otherthan the drain opening itself. lt is possible forthisresson to perfectlyenamel the sink bottom directly up to the drain opening on the plain oreven surface Without the depression or recess,

thereby preventing the loss occasioned by this irregular shape of therecess either in manufacture or after the article has been in use.

A nipple 5 provided with radially extending fingers 6 is passed throughthe drain openlc ing so that the cylindrical iortion of the nip ple 7extends below the ottom portion of the sink. The fingers then rest uponthe inner bottom surface of the sink adjacent to the opening. Thetubular portion 7 is exterior y threaded and a nut 8 engaging the threadcompresses a gasket 9 against the boss 4 forming a water seal. Thetubular portion of the nipple is discontinued considerably below theinner bottom surface of the sink and the fingers 6 are widely separatedas may be seen in Fig. 3 so that. the nipple itself oilcrs noperceptible resistance to the flow of water elven at its lowest levelthrough the drain o ening. Thenipple 5 has a cross-bar 10. T e strainer11 is of inverted dish shape and preferably has a substantially flattop. The Asubstantially vertical side 12 of the strainer is just deepenough to touch the inner bottom surface of the sink and enable the topof the strainer to rest on the tops of the finger 6. At the center thestrainer is depressed in making it, or countersunk to receive a screwhead and a screw 13 Y asses through the strainer at this point andJengages a threaded opening 14 formed in rcross-bar 10. The screw-headrests in the countersink flush with the upper surface of the strainer.The strainer has top openings 1a through which the bulk of the waterpasses, and side openings l5 which extend to the inner bottom surface ofthe sink and permit the escape of water after its level is lower thanthe top of the strainer. in this kind of a drain connection some of thefluid would be trapped in the tub by the strainer.

The drain pipe 16 may be connected to the nipple in any convenient waybut in a preferred construction the pipe is provided with a flange 17which rests against the end of the nipple and a nut 18 en aging thescrew thread on the nipple has a ange 19 inwardly extending and engagingflangev 17 and serving to urge the latter tightly against the end of thenipple.
